Yes. Any equilateral shape can have both rotational and line symmetry.
A semicircle.
A line segment would have rotational symmetry.
A triangle........I think
Parrallelogram (it has rotational symmetry but no lines of symmetry)

Yes, it is possible to have a shape that has a line of symmetry but does not have rotational symmetry. An example is the letter "K", which has a vertical line of symmetry but cannot be rotated to match its original orientation.
How about an isosceles trapezoid
A triangle........I think
Parrallelogram (it has rotational symmetry but no lines of symmetry)
The letters H and Z have both line symmetry and rotational symmetry
A shape does NOT need to have line symmetry in order to have rotational symmetry.For example, the letters N, Z and S can be rotated 180° to show symmetry, but none of these show line symmetry.When the folded part Line of Symmetry. Here I have folded a rectangle one way, and it didn't work.
It has line symmetry (straight down the center) but not rotational symmetry.
A line has rotational symmetry of order 2.
